Probable cause
The pilot receiving instruction's inadvertent application of throttle during the engine start, which led to an inadvertent acceleration and a roll-over.
Findings · 2
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The flight instructor in the weight shift aircraft, which was equipped with a floor mounted, foot operated throttle, reported that upon startup, the pilot receiving instruction inadvertently applied full throttle while putting his right foot on the pedal power control unit. Subsequently, the weight shift aircraft started to move towards a parked jet, so the flight instructor turned the aircraft sharply and the aircraft tipped onto its side. The weight shift aircraft sustained substantial damage to both wings. The flight instructor reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
